It think the one with neji and hinata cause it is a family feud and it says alot about their fight style with is different and it shows family problems and alot more then an average fight or that is what i think

I would say in the preliminaries that i found Shikamaru against that female sound nin most interesting. Getting some indepth on him, and that continues in the finals and in the pursuit of Sasuke after that.

well i used the this ark to get some one into anime and the hinata neji fight he enjoyed but wen i showed him rock lee vs garaa he asked for the first ep i think this is an important tale for this discussion though i could be wrong
